The peripheral nervous system (PNS) is divided into the somatic nervous system, the autonomic nervous system, and the enteric nervous system.However, it is the somatic nervous system, responsible for body movement and the reception of external stimuli, which allows one to understand how cutaneous innervation is made possible by the action of specific sensory fibers located on the skin, as well ...
Cutaneous innervation of the lower limbs is the nerve supply to areas of the skin of the lower limbs (including the feet) which are supplied by specific cutaneous nerves. Modern texts are in agreement about which areas of the skin are served by which nerves , but there are minor variations in some of the details.
In human anatomy, cutaneous nerves are primarily responsible for providing cutaneous innervation, sensory innervation to the skin.In addition to sympathetic and autonomic afferent (sensory) fibers, most cutaneous nerves also contain sympathetic efferent (visceromotor) fibers, which innervate cutaneous blood vessels, sweat glands, and the arrector pilli muscles of hair follicles.

Cutaneous innervation of the upper limbs is the nerve supply to areas of the skin of the upper limbs (including the arm, forearm, and hand) which are supplied by specific cutaneous nerves. Modern texts are in agreement about which areas of the skin are served by which cutaneous nerves, but there are minor variations in some of the details.
A peripheral nerve field can also be described as cutaneous nerve distribution. An area innervated by a single dorsal root is called a dermatome. Neurologists rely on maps of dermatomes and peripheral nerve fields to diagnose areas of nerve damage based on somasthetic or proprioceptive deficits in specific dermatomes and peripheral nerve fields.
Nerves of the right lower extremity Posterior view. (medial calcaneal labeled at bottom left.) Diagram of the segmental distribution of the cutaneous nerves of the sole of the foot.
The inferior clunial nerves (also gluteal branches of posterior femoral cutaneous nerve) are branches of the posterior cutaneous nerve of the thigh that innervate the skin of the lower part of the buttocks. [1] [2] They pass inferior to the inferior border of the gluteus maximus muscle. [2]
